'INVENTOR Patented June 13, 1933 UNITED STATES PATENT orrlcs CLYDE GARDNER, DECEASED, LATE OF EBENSBUBG, PENNSYLVANIA, BY EDNA B. GARDNER, ADMINIS TEATBIX, OF EBEN'SBUEG, PENNSYLVANIA, ASSIGNOE TO GARDNER COMPANY, OF ORANGE, NEW JERSEY, A CORPORATION OF DELAWARE BMISTE'B Application -filed July 12,

The invention relates to improvements in registers and more particularly to improvements in carry mechanism therefor.

The object of the invention is to provide new and im roved means for counteractlng the creep lncident to the operation of crawl type planetary gear carry mechanisms, such for instance as described in Patent No. 1,828,180 issued October 20, 1931 to Clyde Gardner, deceased.

The invention consists in the novel construction and combination of parts, as set forth in the appended claims.

In the above-referred to patent it has been proposed .to utilize an entocyclic construction of totalizer units wherein an inner intermediate gear mounted loosely on an eccentric portion of a spindle, transmits both the actuating movements and the transfer movements to an outer gear wheel secured to the next higher spindle.

Specifically the register, according to the present invention, consists of a series of numeral wheel sets ornnits, arranged side by side upon a series of individual shafts supported by a plurality of sub-frames;

mounted within a shiftable carriage, said shafts being adapted to form in effect a continuous shaft, as hereinafter described and as illustrated in the accompanying drawing, in which: 7

F i 1 is a front elevation of three units, the right hand unit being shown in section, the second unit with the dial sectioned and the third unit in full. 1

Fig. 2 is a cross-section, taken substantially on line 22 of Fig. 1.

Fig. 3 is a erspective detail view of certain parts e ecting a jump carry.

Fig. 4 is a cross-section taken on line 44 of Fig. 1.

Each of the above-notedshafts has on its outer surface. three sections or steps of different diameter, a small diameter left end section 100, a larger and longer right hand section 101 and a short middle section 102 eccentric to the sections 100 and 101; As shown in Fig. 1 the sections 101 are each provided with a recess 103, in which the sections 100 of the lower order shafts are 1832. Serial No. 822,032.

tooth intermediate or transfer gear 108 is rotatably mounted, the teeth of which are longer on that side of the gear (the righthand side) which engages the lateral projections 107 of the receiving gear 106, while at the left hand side the teeth are shorter so that the come into engagement with the pins 109 o the adjoining adding wheel 110 of the higher order only on that side where the radius of the eccentric is longest, said adding wheel being secured to the concentric section 101 of the higher order shaft as shown.

Values inserted into the adding wheels 110, in the manner hereinafter described, may be read by means of the dials 111 secured to said wheels;

To insert values into the wheels 110 any suitable actuating means, such asthe racks described in the afore-mentioned Patent 1,828,180, are rocked into engagement with the broad adding gears 112, loosely mounted upon a transversely extending shaft 113 supported by the frames 105 of the carriage.

To subtract values from. the wheels 110 the carriage may be shifted by any suitable means slightly toward the left, to bring the actuating means into engagement with reverse gears 114, loosely mounted upon the transversely extending shaft 115. Reverse brought into engagement with gears 112 or 114.

Gears 112 have driving connections with their corresponding denominational order receiving gears "106 through intermediate gears 117, whose spindles are rotatably supported by sleeves 118 secured to yoke members 119 of the lower denominational orders, said sleeves being loosely supported at their left hand ends by meansof arms 120, loosely mounted upon the shaft 113.

The lower portions of the yokes 119 pass between the bifurcated portions of corresponding rock arms 121 provided with pins 122 and 123 having engagement with the surfaces 124 and 125 of yokes 119.

Rock arms 121 are splined to the shaft 113, and as said shaft isrocked to either of. two adjusted positions by a suitable setting device (in accordance with the position of the carriage for add or subtract operation) said arms will rock the yokes 119 to bring one of two cam followers 126127 into active relation with the related cams 128129 formed integralwith the hubs of the adding wheels 110.

Assuming the machine to'have been set in additive condition, pins 122 in contacting surface 124 will have rocked the yokes 119 counter-clockwise about point 130 (Fig. 2) to bring the. rollers 126 into engagement with the corresponding order adding cams 128.

Mounted upon each of the sleeves 118 is a spring 131 having extended portions'132 and 133 one on each side of pins 134 and 135, the pins 134 being secured to the yokes 119 and the pins'135 to the frames 105.

The a ove-described rocking movement of the yokes 119 will therefore cause the pins 134 to contact the portions 132 of springs 131 and, the portions 133 of said springs contacting the fixed stops 135, said springs will become slightly tensioned.

' During additive operation, the actuating :means, having engagement with the adding gears 112 as reviously described, will rotate said gears c ockwise, as viewed in Fig. 2, and, through intermediate gears 117, will also rotate the corresponding orer receiving gears .106 in a clockwise direction one tenth of a revolution for each digit value.

As previously described, the semi-circular rojections 107 of thereceiving gears 106 ave engagement with the long teeth of the transfer gears 108, while the shortened teeth of said gears engage the pins 109 of the corresponding adding wheel 110, so that said adding wheels will also be rotated clockwise one tenth of a revolution for each digit value.

As will be recalled, the adding .wheel 110 of the lower order is secured to the section 101 of the shaft of the next higher order unit, and therefore each step movement of gagement of the nine tooth eccentrically I mounted transfer gear 108 with the ten too gear 109 of the higher order addingwheel The following means are provided, however, to accumulate this crawl movement and transfer the same to the higher order wheel only when the wheel of the lower .order passes from 9 to 0.

As previously described, in additive operation, roller 126 is tensioned against the adding cam 128, therefore, as the adding wheel 110 of the lower order is caused to rotate, the corresponding cam 128 will rock the related yoke 119, and pin 123, acting as a fulcrum, will cause said oke to revolve the intermediate gear 117 o the higher order around the gear 112.

This movement of yoke 119 will also serve to increase the tension upon the related spring 131.

Gears 112 being held, by engagement with the actuating means, the above-described movement of gear 117 will impart a reverse or compensating movement to the adding wheel of the higher order, equivalent to the forward movement imparted by the crawl carry mechanism.

However, as an adding wheel of the lower order is moved from 9 to 0 at the completion of a revolution, the roller 126 will be free to fall to the base of cam 128 and yoke 119, under the influence of spring 131,

will revolve gear 117 counter-clockwise about gear 112, to advance the adding wheel of the higher order one-full step movement.

In setting shaft 113 to subtractive position, counter-clockwise movement of crank arms 121 will cause the pins 123 to rock the yokes 119 clockwise about point 130, bringing rollers 127 into engagement with the subtract cams 129.- Counter-clockwise movement of arms 121 will also cause the' of lower order will rotate the register wheels of higher order one step subtractively.

What is claimed is: 1. In a register, means for effecting forward or reverse movement of a numeral wheel, including differential gearing connecting adjacent numeral wheels, one leg of said differential comprisin a primary transmission member driven orwardly or reversely by a lower order wheel, the other leg of said differential comprising a secondary transmission member adapted to counteract the movement transmitted by said first member, and a control device 0 erable by the lower order wheel in either direction of rotation to impart a counteracting move-. ment to said secondary member, and upon passa e of the lower order wheel from 9 to 0 or rom 0 to 9 registering position to impart to the secondary member an equal movement in the opposite direction.

2.
